Warp knit automobile inner decoration facing is widely used in automotive trim, wherein requiring that higher position is column, door-plate and top
Canopy.The warp knit automobile fabric of ceiling portion be typically necessary elder generation and PUR sponge underlays it is compound after go lamination again or with being laminated
It is bottom plate combined.And PUR sponges with fabric complex method will be answered immediately with automobile fabric again after sponge surface scorification with flame
Close.
Flame compound tense sponge surface can be by scorification, and caused smog is more and toxic breakdown products, makes to remain in
Volatile organic content in complex increases, and it is very unfavorable that new cars are prevented with noxious odor.Typically in order to control taste, also
Need subsequently to carry out that processing is exhausted while flint dry, allow smell volatilization in atmosphere.Although this process can be with
The smell of sponge complex is reduced, but also increases cost, and has aggravated air pollution in process of production.It is considered that
